ANDREW ANDERSON, OF GLEN'HAZEL, PENNSYLVANIA.

PROTECTED FLEXIBLE SHOE-SOLE.

Specification of Letters Patent.

Patented Apr. 6,1915.

Application filed November 28, 1914. Serial No. 874,448.

To all whom it may concern Be it known that I, ANDREW ANDERSON, acitizen of the United States, residing at Glenhazel, in the county ofElk and State of Pennsylvania, have invented certain new and usefulImprovements in Protected Flexible Shoe-Soles, of which the following isa specification.

This invention relates to protected flexible shoe soles, and one of theprincipal objects of the invention is to provide a steel wire havingpoints or prongs formed there on for securing the wire in loopsextending back and forth across the sole of the boot or shoe to form aprotecting wear surface, and said wire being also provided withprojecting studs which serve to prevent slipping.

Another object of the invention is to provide a protector for the soleof boots or shoes comprising a steel wire having prongs projecting fromopposite sides thereof, said prongs being welded or connected to thewire in any suitable manner and said wire being bent in loops or in zigzag form to practically cover the sole of a boot or shoe in parallelstrands properly spaced apart to serve as a protector and ice creeper.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,

Figure 1 is a. bottom plan view of a shoe sole having a protectorsecured-thereto and made in accordance with this invention, Fig. 2 is atransverse sectional view taken on the line 2-2 of Fig. 1, Fig. 3 is aperspective view of a short length of the wire, Fig. 4 is a plan view ofa short 'section of wire in which the prongs are triangular in formincross section, Fig. 5 is a similar view showing the points or prongs ofrectangular form in cross section, and Fig. 6 is a similar view showingthe prongs of half round wire in cross section.

Referring to the drawing, the numeral 1 designates the sole of a boot orshoe, and 2 is the heel thereof. The sole protector comprises a steelwire 3 provided with a plurality of spaced prongs 4 extending from oneside of said wire, said prongs adapted to be driven into the sole 1 ofthe boot or shoe to hold the sole in place. The wire 3 is looped uponitself as shown by bending the ends in curved form as shown at 5 fromopposite ends and leading the wire in a zig zag form from one end of thesole to the other, the loops at the middle being longer as at 6 than theend loops 5 and 7 and the strands 3 lying'parallel one with the otherand spaced apart about the same distance from the other.

The wire strands 3 are each provided with projecting studs or calks 8which are spaced apart throughout the length of the wire, and thesecalks serve the desirable purpose of preventing slipping, and alsoassist in taking the wear of the sole. As shown in Fig. 3, the prongs 4and the calks 8 are in the form of a pyramid, and in Fig. 4, the prongsand calks are triangular as shown at 9. As

shown in Fig. 5 the calks and prongs are rectangular as shown at 10,while in Fig. 6, the prongs are half round, as shown at 11.

From the foregoing it will be obvious that a shoe sole protected asdescribed will-be flexible from end to end and that at the same timewill be provided with a protecting wear element which can be readilydriven into the sole to hold it in place and will also be provided withprongs or calks for preventing slipping.

Various changes may be made in the details of construction withoutdeparting from the spirit and scope of the invention as defined in theclaim.

WVhat is claimed is A shoe sole provided with a wire protector formed ofsteel and having prongs projecting into the tread surface of the sole tohold the protector in place, said wire being extended back andlforthacross the sole, said wire having calks or prongs extending downwardlyfrom the protector to prevent slipping.

In testimony whereof I affix my signature in presence of two witnesses.

I ANDREW ANDERSON. Witnesses:

GEO. MILLER, H. MELAN-DER.
